(54) Imaging element comprising an electrically conductive layer containing conductive fine particles


(57) Imaging elements, such as photographic, electrostatographic and thermal imaging elements, are comprised of a support, an image-forming layer and an electrically-conductive layer comprising a film-forming hydrophilic colloid having dispersed therein both electrically-conductive fine particles and pre-crosslinked gelatin particles. The combination of hydrophilic colloid, electrically-conductive fine particles and pre-crosslinked gelatin particles provides a controlled degree of electrical conductivity and beneficial chemical, physical and optical properties which adapt the electrically-conductive layer for such purposes as providing protection against static or serving as an electrode which takes part in an image-forming process.
